IMHO -- PS3 selling on par with X360 is good
In fact it is doing better than XBOX360 considering the two years PS3 has been in the market have been in a terrible economic climate at a much higher price of entry.

Current sales of PS3 ---
22,237,206 * 399.99 = 8,894,660,027.94
Sales of XBOX360 after the same amount of time
18,731,985 * 299.99 = 5,619,408,180.15
In the same amount of time Sony has sold merchandise worth $ 3,275,251,847.79 more but since Sony has been selling its product at a greater loss than Microsoft it is expected to operate at a loss until critical mass is reached.
I think selling products worth $3Bn more is impressive in this economic climate.
P.S. these numbers are not going to be exact since PS3 has an initial point of entry of $599.99 and xbox360 of $399.99. However, this illustrates my point rather well.
